Case studies

The challenge

The group ran plants across three generation technologies, with equipment from different vendors and mixed communication protocols. The whole fleet had to be brought into a single operations centre, with an integrated view, reliable communications and security fit for critical infrastructure.

The solution

An end-to-end project, from design to go-live:

• Network and IT infrastructure: communication architecture between the plants and the centre, servers and operator workstations.
• Control room layout: arrangement of operator positions and display walls.
• Cybersecurity: OT/IT network segmentation and secured access to the control environment.
• Automation and control: integration of field signals over IEC 104, DNP3 and Modbus.
• SCADA development: operator screens, alarms and consistent supervision across all technologies.

The challenge

Generation and transmission companies rely on the systems in their plants and operations centres being available at all times: these are mission-critical environments where a failure directly affects operations.

The solution

Ongoing outsourcing services, working directly in:

• Power plants: support for local infrastructure and operating systems.
• Operations centres: support for supervision systems and the infrastructure behind them.

The challenge

Power plants combine systems and components from different generations and vendors. Their actual security posture had to be established and the whole environment brought to a secure, documented state.

The solution

Work across three fronts:

• Assessment: security evaluation of the plants' systems and components.
• Remediation: definition and implementation of the measures needed for every system and component to operate in a secure environment.
• Documentation: development of information security management documentation.
